Wiring diagram
See Figure 4-1: AVIATOR 700S system (minimum, AC powered) for the wiring for
an AVIATOR 700S System with the HPA-5015 MCHPA
For the requirements to RF cable see Recommended RF cables on page 4-38 on pin TP71.
Pins for the MCHPA/CSDU
4.3.7 To wire the MCDU 1, 2 and 3
ARINC-781 compliant.
The CSDU has interfaces for three high or low speed ARINC-429 interfaces for
communication with MCDU #1, MCDU #2 and MCDU #3. For cable requirements see
Recommended cables for ARINC 429 on page 4-38.
Description
The Multi Control and Display Unit (MCDU) interfaces allow the CSDU to be managed
from a cockpit control panel. The CSDU uses MCDU protocol standards defined in
ARINC Characteristic 739 or WSCI (see ARINC 741, Part 2, Attachment 2F-42.1).
Display and control details may be manufacturer-specific.
Wiring diagram
See Wiring – overview on page 4-7.
Pins for MCDU 1, 2 and 3
Note
During installation, measure and write down the cable loss of the RF cables. See
section 4.3 for the maximum loss requirement at 1.6 GHz.
